Application filed December 2, 1904. Seral No. 235,261.

applying cement or other liquid material to.

stock and particularly to machines for applying cement to shoes.

The invention is herein shown as embodied in a machine adapted for coating the bottoms of Goodyear shoes with cement preparatory to the sole-laying operation, the cement being employed for the purpose of holding the outersole temporarily on the shoe and" for forming a tight joint between the outersole and the welt, inseam, and filling when the outersole has been attached permanently by the usual line of stitches.

The machine comprises a reservoir from which the cement is delivered as needed to a cement-applying means, herein shown and referred to as a brush, but which may be any other suitable device adapted to apply a coating of cement to the surface of the work. The cement commonly used includes as a solvent a volatile liquid, such as naphtha, and consequently the cement dries rapidly and becomes thick and stif when eXposed to the atmosphere. On this account, for the reason that a small quantity only is required for each shoe, it is advantageous to discharge the cement intermittently on the cement-applying brush and then to' spread or distribute it over the working face of the brush. For the purpose of coating the welt, inseam, and filling of a shoe the brush must be of co-nsiderable Width and an important feature of the present invention consists in novel means for spreading the cement upon the cementapplying brush. As herein shown, the cement is delivered upon the brush in a stream near one edge of the brush and means is provided for 'working the cement laterally over the width of the brush. The means for spreading the cement may be a bar, plate, or other suitable device J. BURNS, a

rotating brush across the arranged in proximity to the face of the brush between the delivering means and the work for guiding and working a portion of the cement delivered on or carried by the face of the brush to'ward'the opposit-e edge. This obj ect preferably will be effected by arranging the spreading means obliquely across the face of the brush whereby the cement will be urged across the brush towarcl the edge thereofengaged by the rear end 'of the spreader, or the bristles which form the Working face of the brush may be arranged in rows extending obliquely across the face of the brush and the spreader arranged at an angle to the length of the rows of bristles so that the cement will be worked along the oblique rows of bristles toward one edge of the brush.

Cement of different brands and grades varies in thickness or consistency and a machine in which the spreader is arranged to distrbute properly one kind of cement sometime will not under the same conditions distribute satisfactorily a differentkind of cement. In view of this fact and because it is sometimes desirable to vary the relative amounts of cement carried by different portions of the brush I preferably provide means for controlling the relative quantities of cement carried by different portions of the brush. This may be accomplished by means arranged to engage the whole or a portion of the face of the brush for wiping or working more or'less of the cement off from certainportions and, it may be, tran ferring said excess of cement to other portions of the brush. I have herein provided a scraper arranged to engage the face of the brush and adjustable into different angular positions with relation to the aXis of rotation of the brush whereby it may be made to scrape the cement carried by the brush fron either side of the brush toward the other side. This means for controlling the relative quantities of cement carried by different portions of the brush is independent of the means for spreading or distributing the cement over the face of the brush, but of course said spreading means might be constructed and arranged to cause different relative quantities of cement to be carried by diflerent portions of the brush, or said spreading means might be made adjustable for varying the relat-ive quantities of cement which shall be applied to different portions of the brush face. I have herein shown one means for adjusting the spreading bar for this purpose.

The lilling material which is applied over the innersole between the inseams for build.- ing' up this portion of the shoe bottom flush with the top of the inseam is usually composed of ground oork, leather trimming, or other fine granular material mixed with cemeut to form a paste. This material requires to be in a soft Condition when applied and it does not adhere with much firn ness to the sole until it has stood for some time to allow the cement to set. A di'iiculty has been experienced in cementing the bottoms of shoes while the filling is still soft, because the cement-applying means is liable to loosen the filling material from the innersole and strip it from the shoe. To overcome this diiiiculty I have provided a novel construction of cement applying means having' an acting face one portion of which is soft and yielding and is adapted to coat the filling with cement without loosening the filling from the innersole, said acting face having another portion which is firmer and well adapted for coating with cement the uneven surface of the inseam and welt. To this end the different portions of the acting face of the brush may be made of different materials, as, for example, the portion engaging the filling may bristles, while the portion engaging' the inseam and welt is made of stiifer bristles.

It is found in practice that the brush is liable to pick up loose particles of the filling' material, which, if allowed to accumulate upon the brush and be carried around with it, would interfere with the operation of the brush to an objectionable extent, and to overcome this diii'iculty I prefer to employ means for engaging' the brush in the rear of the point where the brush acts upon the work, said means serving* to scrape or remove from the brush any particles of the filling or other foreign material which may have been picled up from the work. The means for removing these particles is herein shown as a bar arranged to extend obliquely across the face of the brush in position to scrape or strip off any particles of fillingmaterial which the brush has pioked up from the work. This bar may be the bar or scraper before referred to as employed for controlling` the relative quantities of cement carried by different portions of the brush, as has been before described.

Other features of the invention, including details of construction and combinations of parts, will be hereinafter described and pointed out in the claims. v

adjusting the spreader, and Fig. 8 is a view of a portion of the machine taken from the right as shown in F 7.

The cement is supplied from a reservoir 'through a conduit 2 which is normally closed by a gate 4- adapted to be operated ,nianually by any suitable means, as, for eX- -ample, by a connection with a foot treadle. 'The cement is delivered to the face of the 'cenient-applying means, which is herein :shown as a rotary brush 6 and referred to as 'a brnsh, but which may be a roll or any other means adapted for the purpose. The brush is carried on a shaft 8 provided with. a pulley 10 by which it may be continuously rotated. The brush. is of a Width suitable for applying a coating of cement to the welt :and inseam and preferably a portion of the 'filling of a Goodyear shoe, whereby the operator is enabled by passing' each side of the shoe once under the brush to coat the entire welt and the inseam, and either the whole or the marginal portion of the surface of the filling which occupies the middle portion of the shoe bottom between the inscams. The cement requires to be spread over the face of the brush in order that the surface of the work engaged by the face of the brush may be properly coated, and l bavefor this purpose provided a spreacler '12, herein referred to as a bar, but which may be a rod, plate, or other suitable device, and which is shown as arranged across *the face of the brush between the cementdelivering means and the place where the brush engages the work.

T he cement is shown as delivered to the brush .near the inner edge of the acting face of the brush and the spreader is arranged for working and guiding the eement across the face of the hrush toward and preferably to its outer edge, whereby the cement is distributed across the face of the brush. The arrangement of the spreader with relation to the brush may be varied according' to the construction of the brush.

l, have shown in Figs. 2, 3, and %t a brush in which the bunches of bristles are arranged in .rows extending obliquely from the inner edge of the brush downwardly and outwardly toward the outer edge of the brush I viewing Fig. 3. This arrangement of the bristles has the advantage, among others, that the peripl'ery of the brush as a whole presents more nearly a true circle than is presented by a brush in which the bristles are arranged in rows extending parallel with the axis and present intervening spaces tending to give the brush a polygonal shape. In said Fig. 3 I have shown the spreader as eXtending downwardly and outwardly substantially parallel with the rows of bristles. In this arrangement the outer end of the spreader is lower than the inner end with which cement delivered to the brush first comes in contact, and the cement is therefore worked and guided downwardly along the spreader and across the face of the brush, being impelled by gravity in that direction.

In Fig. 5 1 have shown a section of a brush in which the bunches of bristles are arranged in rows parallel with the aXis of rotation of the brush and in this figure the spreader is located at an angle to the rows of bristles and therefore at an angle to the aXis of rotation of the brush. With this arrangement the spreader will work the cement delivered to the brush laterally along the row of bristles from the end of the row which first engages the spreader toward the opposite end of the row.

In Fig. 6, and in full lines in Fig. 7 1 have shown both the rows of bristles and the spreader as extending obliquely across the face of the brush, the spreader, however, being arranged at an angle to the rows of bristles. A brush having its rows of bristles arranged obliquely presents, as has been eX- plained, a surface which closely approximates that of a cylinder so that the spreader coperates with it more satisfactorily for that reason. Aside, however, from the cylindrical surface presented the arrangement of oblique rows of bristles with a spreader which is oblique to them serves to maintain the cement on the tufts on each row rather than to cause it to be forced in between the rows. Considering Fig. 4:, for example, it will be evident that the cement deposited upon the inner tufts of any given row of bristles will strike the obliquely arranged spreader before the remaining tufts pass beneath it so that the cement will tend to be spread over the tops of the tufts.

In the following description and in the claims the term oblique as applied to the cement spreader and to the scraper, Whluh is hereinafter described, will be used to desi nate either an angular relation to the aXis of rotation of the brush or an angular relation to the rows of bristles which form the working face of the brush.

The spreader is shown in Figs. 1,?, and 3 as projecting upwardly and laterally from a plate 16, said plate being located adjacent to the side of the brush so that as the cement works along the spreader toward its lower end the plate will constitute an abutment or dam for holding the cement and preventing it from dripping off from the lower end of the spreader.

The upper end of the spreader may be supported by a second plate 18, as shown in Fig. 3, and in the illustrated embodiment of the invention the plates 16 and 18 are connected at their lower sides and constitute a frame for supporting a plate 20 which is adjustable toward and from the periphery of the brush by means of a hand screw 22. The plate 20 may be employed if desired as a doctor for regulating the quantity of cement carried on the periphery of the brush. In case the brush becomes too heavily loaded the superfluous cement will be temporarily removed by the doctor and will pile up between the end of the doctor and the periphery of the brush, as shown in Fig. 1, until a portion of the cement carried by the brush has been transferred .to the work. The frame, comprising the side walls 16 and 18, is adjustably attached to a bracket 2 1 projecting from the machine frame, as shown in Fig. 2, and may be moved for placing the spreader at different distances from the brush.

That portion of the surface of the work formed by the welt and inseam presents an irregular face, as indicated in Fig. 1, and in order to coat properly this irregular face it is necessary to employ in a cement-applying brush bristles of considerable stiffness which will enter the depressions in the work. It is the practice, howe'ver, to cement shoe bottoms shortly after the filling material has. been applied and before it has become sufficiently set to adhere firmly to the innersole. In view of these facts 1 preferably employ a cement-applying brush having a portion for engaging the filling which is softer and more fleXible than the portion which engages the inseam and welt and which is, therefore, less liable to loosen or strip the filling from the innersole. viewing Fig. 4 the left-hand side of the brush is the softer portion for engaging the filling material, while the right-hand side of the brush is stiffer for engaging the uneven surface of the inseam and welt. Preferably 'the portion of the brush which engages the filling material is composed of relatively soft, flexible bristles, while the portion of the brush which engages the welt and inseam is formed of coarser and stifer bristles. In Fig. 5 is shown a brush comprising a tapering or cone-shaped hub 141, the base or larger end of which carries the bristles for engaging the welt and inseam, while the end having` the smaller diameter carries the bristles for engaging the filling.

It is found' in practice thatthe brush loosens from this filling material some particles which are carried around by the brush and it is desirable to provide means for removing these particles from the working face of the brush. 'For this purpose 1 have provided a bar or plate 30 arranged obliquely across the face of the brush in position to strip or scrape 'from the brush any particles which have been piclcd up from the work. The scraper is shown long enough to act on the whole width of the brusln but it might be made shorte and act only on the portion of the brush which engages the tilling material. the scraper is provided with a shank or bar secured by a binding screw 34 in. a. clainp 3 The scraper is preferably located at the rear of the brush and it may be moved toward and from the pcriphery of the brush and secured in adjusted position by the binding serew 84.

The titferent brands and gradcs of commercial cenient vary in thickness or con-- sistency, and it is found that such different kinds of ceinent are not distributed uniformly by a spreader occupying any given position with relation to tle brush. Also it is sometimes desirable when using the same hin d of ceinent to apply a thicker coating to one portion of the worl: than to another, and I have therefore provided means for controlling` the relative quantities of ceinent carried by different portions of the brush. The bar or plate 30, above. described as being adapted to scrape ofi' particles of ,tilling material which may adhere to the brush, may be employed if desired for controlling the relative amounts of cenient carried by different portions of the face of the brush by adjusting said bar or platc into proper contact with 'the brush and into different angular positions with relation to the face of the brush. By adjusting it into the lower position shown in dotted lines in E a'- it will wipe the ceinent from the rightdiand portion of the brush viewing said figure and guide or work it toward 'the left-hand or outer edge of the brush, thereby increasing the relative uantity of cement which will be applied to the filling material; and by adjusting the soraper into the upper position shown in dotted lines in at it will wipe the cement from the left-hand portion of the brush and guide and worl: it toward the right-hand or inner side of the brush, thereby increasing the amount of cement which will be applied to the welt and inscam.

lt, is to be noted that the bar or plate 30 constitutes means independent of the spreading means for controlling the quantity of cement carried by different portions of the face of the brush. in Fig. 7 I have shown the spreader 121 to be arranged for adjustinent into different angular positions with relation to the brush, and it will be Obvious that by inclining the spreader more or less or by changing its inclination toward one side or toward the other of the brush the distribution of the cement over the face of the brush may be controlled and the brush eaused to apply to different portions of the work the desired relative quantities of cement. The spreader is shown in Fig. 7 as having on one end a lug %to which received loosely in a socket in the wall 1.8. The opposite end of the spreader is reduced in size 'and has a square portion %LB which extends through and is guided in a slot 44 in the wall 16. The end portion of the spreader outside the wall 16 receives a plate +t6 and a binding screw 48. By loosening the binding screw the spreader may be moved from the full line position shown in the figure toward either of the dotted line positions and so Vary the distribution of the cement over the face of the brush. The plate 46 covers the slot in the wall 16 and prevents the escape of oement.

It is found in practice that small quantities of cement work from the hub oi' the brush onto the shaft 8 and find their way into the shaft bearing, thereby *ausing the shaft to run hard. To overcome this (liliiculty I have provided the brush shaft with a collar 50 located between the shaft bearing and the brush hub and spaced away from each of these parts as shown. The collar acts as a dam or wall to stop the cement from working along` the shaft from the brush toward the bearing. Preferably the collar will be formed with a beveled face on the side adjacent to the brush for more eftectu` ally guarding against the passage of cement beyond the eollar.

n the use of the invention the brush is preferably rotatcd continuously and the work is supported in the hand of the operator. The gate is opened to permit the ment. to flow on the brush and be spread or distributed over the face of the brush as the latter rotates in contact with the spreader. The shoe is presented as indicated in Fig. l, against the welt crease guide 59 and moved under the brush to cause the bottom of the shoe to be coated from one end to the other, the cement being applied first on one side of the shoe bottom and then on the other. If the desired relative quantities of cement are not being applied to the iilling material and to the welt and inseann the angular position of the bar or plate 30 with relation to the face of the brush may be changed or the spreader may be adjusted to cause more or less of the cement to be carried by eithor side of the brush.

lt is sometimes desired to eement the bottom of the shoe before the filling material is applied between the inseams and the nia-- ehin-e is used in the same way for this purpose, the only difference being that cement is applied to the face of the inner sole instead of being appiied to the filling material.

lVhile for convenience ,l have described my invention as embodied in a machine for applying cement and have in the specifica- V of the brush.
